Now, we consider the case of \(b < m+n\) ; an instance of this
scenario, by letting \(m \gg n\) , can adequately model the reverse
link of the
celebrated massive-MIMO channel [1]}.
In presence of uncorrelated block-Rayleigh fading, the
high-SNR capacity-achieving input structure, as already mentioned, departs from the equal power
allocation and is Beta distributed. We provide herein the output pdf for a block-fading channel fed by BSTM [2]}.
